The narrative follows a caravan route from Red Sea ports inland across coastal plains, salt lakes, and elevated tablelands toward the kingdom of Shoa. It combines practical travel journal entries with geological and hydrological observations, notably on the Hawash basin and local watersheds. Encounters with diverse tribal groups provide detailed descriptions of customs, justice, commerce, slavery, and periodic raids that shape movement and security. Natural-history remarks, accounts of camp life and negotiations with local leaders appear alongside reflections on language, orthography, and the hardships of long-distance travel in a little-charted region.
